| 摘 要： | 在靖边油区油井施工中,白垩系下统洛河组砂岩底部泥浆漏失概率42%～66%,而砂岩其它部位未出现漏水现象。侏罗系中统安定组与上覆洛河组呈角度不整合接触,古风化壳的存在使安定组顶部灰岩裂隙十分发育,最大漏失量达0.88m3/mm。故洛河组砂岩底部与安定组泥灰岩是靖边油区开发地下水的较佳部位。

| Abstract: | Through analysed on hydrogeological characteristics of aquifers in sandstone of Luohe formation and marlite of Anding formation discoverred by prospecting petroleum wells, consider that in the bottom of Luohe formation sandstone there are many pores and showing clinounconformity between Anding formation of mid Jurassic series and Luohe formation of lower Cretaceous series, ancient crust of weathering make marlite in top of Anding formation developed fractures, So primarily defined that bottom of Luohe formation sandstone and marlite of Anding formation are optimum layer location of water search in Jingbian oil area. |
